AUTOMATIC iViESURlNG-TAN K.

SPECIFICATION forming part of Letters Patent No. 716,539, dated December23, 1902. Application led May 1,1901. Serial No. 58.369. (No model.)

.T afl/ whom it may concern:

Be it known that I, JOSEPH E. HARTMAN, a

citizen of the United States, residing at Clevefluid is drawn from thetank as required and in predetermined quantity and automatically shutsoff when the required quantity is delivered.

The object of my invention is to provide a iiuid container or tank whichis provided with a vertically-adjustable intake, which is lowered thenecessary and predetermined distance beneath the liquid-surface in thetank to allow of a certain and predetermined amount of liquid to bedelivered through said intake and from thence pass out of the containeror tank and into a portable can or the like. A11 adjusting device isalso provided for raising and lowering the intake, and a registeringdevice or index is connected, whereby the measuring is accomplished.

In the drawings, Figure I is a view in elevation of a tank constructedaccording to my invention. Fig. II is a vertical sectional View of thetank, illustrating its internal construction. Fig. III illustrates mypreferred construction of mechanism for operating the intake. Fig. IV isa sectional view of a valve mechanism employed to prevent leakagethrough the intake. Fig.Villustrates a modified form of faucet, which isadjusted vertically; and Fig. VI illustrates a sectional View of myimproved dial or pointer.

A represents a casing which is formed into two compartments-viz., anupper compartment A', which is adapted to contain the duid, and a lowercompartment A2, which supports the compartment A' and also acts as achainber for receiving and protecting the delivering-pipes and aportable utensil to which the liquid is delivered.

B represents the mouth of the intake, which is preferably formedfunnel-shaped and communicates with the adjustable intake-pipe B', uponthe upper end of which said mouth B is mounted. The intake-pipe B'telescopes within tube C, with which it forms a fiuidtight slip-joint,so as to adapt said pipe B' to be raised or lowered, and 'with it theintakemouth B.

My preferred mechanism for raising and lowering the intake-mouth B andpipe B' consists of a vertical rack D, which is attached at the lowerend to the intake-mouth B or pipe B', and a pinion D', mounted on aspindle D2 and meshing with said rack D.

E represents a bearing-block which forms a bearing for spindle D2 and aguide for the rack D. (Seen more-clearly in Fig. III.)

f represents a valve which is adapted to seat itself upon the upper endof the intakepipe B' and close the same tightly. The valvef is in turnsecured in a suitable manner, such as by means ofan arm f', to anannular cork float F, which is hinged at one side in the intake-mouth B,(see Fig. IV,) thus allowing said valvefto open when the mouth B isbetween the surface of the duid in the container or tank and to closewhen the surface of the Iiuid has reached the upper rim or surface ofthe intake-mouth B, as will be hereinafter described.

In Figs. I and VI, I have illustrated my improved dial and pointer,which is especially adapted to indicate and predetermine the amount ofiiuid which is to be drawn from the container or tank, and the sameisconstructed as follows:

G represents a pointer which is secured to spindle D2 in such a manneras to rotate said spindle and with it the pinion D'. The pointer G isformed in two parts, one, g, of which is slidable within the other. Thepart g is provided with a projection g', which slides in an opening orslot formed in the part g and engages a spiral way or run h, formed onthe face of the dial H, and thus is projected or retracted according tothe direction in which the pointer Gis rotated. Divisions and marks h'are formed on the face ofthe dial and arranged so as to indicatehalfpints, pints, quarts, and gallons or the like quantity of fluidmeasure. These marks are arranged in a spiral to correspond with the wayor run h, so that the indicating end of the pointer will follow a spiralpath.

The pipe C extends downward, as illustrated in Fig. II, and from thenceupward and outward by branches C and C2, respectively. The ,horizontalpipe C2 is turned downward and provided with a -faucet C3, which formsthe outlet for the fluid measured off within the tank by lowering theintake-mouth B. Avertically-adjustable eX- tension C4 may be provided atthe outlet end of the faucet C3, said extension being funnelshaped atits lower end, so as to enter narrow-necked bottles, cans, or jars.

The operation of my device is as follows: The tank A being supplied witha suitable quant-ity of fluid, the intake-mouth B being raised above thelevel of the surface of the fluid, the mouth B of the intake is nowlowered, so that its upper end will be just level with the surface ofthe fluid in the tank and the dial I-I and pointer G set at zero. Whenit is desired to draw off a certain quantity of fluid, the intake-mouthB is lowered the required distance beneath the surface of the liquid inthe tank by turning the pointer G along the face of the dial to therequired mark on its face. The faucet C3 being closed the air in thepipe C will force the valve f open until the required amount isdelivered from the tank by opening the faucet C3. When the surface ofthefluid in the tank has reached the level of the upper end of the intake,the iiuid stops flowing and the valvef closes automatically and stopsany drip through the faucet C3.

The object in forming the dial with aspiral guide-run h and spiral marksfor causing the pointer to indicate different quantities is to preventmistakes in measuring on account of the different cross-section areas ofthe container or tank at different levels.

What I claim isl. In a measuring device of the type set forth, thecombination with the tank or container divided into an upperliquid-receiving compartment and a lower compartment to receive adelivery-pipe, of a vertically-adjustable intake-pipe communicating withsaid tank and telcscoping with said delivery-pipe, a flaring mouthcarried by the upper end of said intake-pipe, an annular iioat hinged tothe inner Wall of said mouth, and a valve connected to the oat by aspring, said valve adapted to normally close the inlet to theintake-pipe.

2. In a measuring device of the type set forth, the combination with thetank or container divided into an upper liquid-receiving compartment anda lower compartment in which latter a deliverylpipe is arranged, of a'riesce vertically-adjustable intake-pipe having a mouth at its upperend, a iioat hinged within said mouth, a spring-held valve carried bythe oat and normally closing the inlet to the intake-pipe, and means foradjusting and determining the adjustment of said intake-pipe,substantially as described.

3. In a measuring device of the type set forth, the combination with avertically-adjustable intake-pipe, a tank or container divided into anupper and a lower compartment, the upper compartment to receive theliquid and within which said pipe is adjustable, a float located at theupper end of said intakepipe, and a spring-held valve carried by saidfloat for normally closing the inlet to the intake-pipe, substantiallyas described.

4. In a measuring device of the type set forth the combination with atank or container of an adjustable intake-pipe having a mouth secured toits upper end, an annular ioat hinged within said mouth, a spring-heldvalve carried by the float and normally closing the inlet to theintake-pipe, means conveying the liquid from said intake-pipe anddelivering the Same, and means for regulating and determining theadjustment of said pipe substantially as set forth.

5. A dial and pointer for measuring devices of the type set forth,comprising a dial-plate havingl spirally-arranged indicating-marks, aspirallyarranged way on the dial-face, and a pointer made in twosections G, g, the latter telescoping in the former and having its innerend turned at an angle to engage in the spiral way and travel in a slotprovided therefor in the section G, whereby the telescoping section g ofthe pointer is forced outward or drawn within the section G, a shaft onwhich both dial-plate and section G of the pointer is mounted, and meansfor rotating the shaft and pointer in unison, substantially asdescribed.

6. In a measuring device of the type set forth the combination with atank or container of a vertically-adjustable intake-pipe connected to arack and having a mouth at its upper end, a float carried by the mouth,a valve carried by the float for normally closing the inlet to theintake-pipe, and a pinion engaging said rack, with means connected tosaid pinion whereby the rack and the attachedintake-pipe is adjusted ormoved in a vertical direction, substantially as set forth;

Signed by me at Cleveland, county of Cuyahoga, and State of Ohio, this9th day ofMarch, 1901.
